General Description
DL series pump is vertical multi stage single suction segmental centrifugal pump. It can delivery clear water or other liquid which is physically or chemically similar to clear water. The temperature of the liquid is 0 ℃-80 ℃. The inlet pressure of pump should be less than 0.6MPa.
DL series pump is vertically installed with advantage of compact structure, low noise and space saving. It is widely used for feeding water in high buildings in city, heat supply system, fire control system, air conditioning system and water supply systems.
Performance range
Capacity: 8-432m³/h
Head: 20-280m

Instruction of pump type

For example:65DL32-15X5
65：Inlet diameter of the pump is 65mm
DL：Vertical multi stage centrifugal pump
32：Rate flow 32m³/h
15：Rate head of each stage 15m
5： Pump stage is 5

Structure
The inlet is located in suction stage under pump; the outlet is located in discharge stage above pump. Both of the inlet and outlet are horizontally mounted. The outlet can be installed with the angle 90°,180°and 270°against the inlet according to users’ requirement (usually the inlet and outlet are codirectional ) . The main part of pump consists of suction stage, middle stage, discharge stage, diffusor, bearing frame, shaft, impeller, balance drum and shaft sleeves. The axial force is balanced by balance kettle and the remaining axial force is borne by upper radial thrust force ball bearing. The sealing ring is separately mounted in suction stage and middle stage to prevent high pressure water from leaking.
The radial thrust force ball bearing is mounted above shaft and the sliding bearing which gets lubricated by grease is mounted under shaft. Shaft seal is available with soft packing seal and mechanical seal, and the seals can be lubricated and cooled by pressure water in balance chamber. The pump is driven by vertical motor. View from motor end, the rotating direction of pump is counter clockwise.

Q:I'm just wondering where I should buy my new water pump for my 2.2 cavalier? Auto zone, carquest, checker? Does it matter which one?Thanks: It does make a difference. Autozone and the other discount places carry cheap poorly made items. Go to NAPA.

Q:ive been doing repair work on an old 86 jeep cherokee and when i let it idle there is a water leak, me and my dad came to the conclusion there was something wrong with the water pump. i cant find the manual and i dont even know what im looking for, so where would i find the water pump and how would i go about replacing it?: For 2.5L 4.0L Engines Some vehicles use a serpentine drive belt and have a reverse rotating water pump coupled with a viscous fan drive assembly. The components are identified by the words REVERSE stamped on the cover of the viscous drive and on the inner side of the fan. The word REV is also cast into the body of the water pump. 1. Disconnect the negative battery cable. 2. Drain the cooling system. 3. Disconnect the hoses at the pump. 4. Remove the drive belts. 5. Remove the power steering pump bracket. 6. Remove the fan and shroud. 7. If equipped, remove the idler pulley to gain clearance for pump removal. 8. Unbolt and remove the pump. To install: 9. Clean the mating surfaces thoroughly. 10. Using a new gasket, install the pump and tighten the bolts to 13 ft. lbs. (18 Nm). 11. If removed, install the idler pulley. 12. Reconnect the hoses at the pump and install accessory drive belt. 13. Install the power steering pump bracket. Install the fan and shroud. 14. Adjust the belt tension and fill the cooling system to the correct level. 15. Operate the engine with the heater control valve in the HEAT position until the thermostat opens to purge air from the system. Check coolant level and fill as required.

Q:Do I need to change the water pump if I replace the timing belt ? and does the water pump connect with the timing belt ? if the water pump goes out will it bend the rods ?: i would get out of that thing they are nothing but trouble always! a have a freind got a nice chevy ,never been happier?

Q:Would I notice a difference in driving if I changed my timing belt and water pump?: If nothing's wrong with them, no you won't feel any difference

Q:a picture of a water pump and its parts,picture of cross section of a water pump how water pump works: A pump is a device used to move liquids, or slurries. A pump moves liquids from lower pressure to higher pressure, and overcomes this difference in pressure by adding energy to the system (such as a water system). A gas pump is generally called a compressor, except in very low pressure-rise applications, such as in heating, ventilating, and air-conditioning, the equipment is known as fans or blowers.

Q:What is the easiest way to remove a water pump?: drain radiator. remove both 21mm motor mount bolts from subframe (front and rear). drain radiator. remove overflow/washer bottle. remove drive belt. remove 8mm bolt that hold lower watertube to front cover. remove lower water tube from water pump. remove heater hoses from water pump. slightly lift engine with floor jack. remove water pump pully. remove water pump. if you still cant get it you will need to remove the 4 studs that go through the water pump. now its just that easy to do

Q:what water pump is on a 1978 mercruiser 170hp 224cc 3.7 liter: Got no partnumbers but.. the 3.7 is a Ford engine and dont know from your question if you mean the circulation pump on the front of the engine or the raw water pump in the outdrive. This engine has a closed cooling system and uses coolant to cool the engine pumped around by the circ. pump on the engines front. The water to cool the heat exchanger (and so the coolant) is pumped up by the outdrive pump. Mostly when the engine runs hot the outdrive impeller is worn out and need to be changed or the raw water system can be cloged up by debris.

Q:I am taking my car in for a timing bell replacement. My car is a honda accord 2001 6 cycl. The mileage is 80K still way under the manufacturer recommendation. I am thinking of replacing the oil pump and water pump. I am thinking that since the engine is already opened might as well get this done. I don't know if this is necessary. Are these items even closed to the timing belt area? Does anyone have any recommendation when this should be done ?: Oil pump should be replace when engine is getting rebuild Oil pump at 80k = no Water pump with timing belt is preventive maintnanace thing. To replace water pump require removing timing belt. Most people just go ahead and pay extra to have water pump replace at same time with timing belt. Shop should just charge your cost of parts for water pump and coolant. water pump with timing belt is your call.

Q:I have a 1997 Pontiac Grand Prix 3.8 v6 engine. My car has been overheating lately and my low coolant light came on so i put antifreeze in it and the light went off. I drove about 3 blocks and the low coolant light came back on again and the thermostat was at the hot mark so i checked the antifreeze and it was just about empty. I did noticed when I was pouring the antifreeze that some did run out the bottom of the car but it wasn't alot. Also I noticed that in the morning when I get up and drive my car the thermostat could be at cold but if I drive about 3 blocks it's almost at the hot mark. Please help me determine whats wrong with my car. Is my water pump bad?: It could be a number of things. What you need to do is fill it up and run it until it gets to operating temp checking for leaks while its running. If you see the fluid coming from the front of the engine it more than likely the water pump. It could also be a bad cap letting water by a hole in the radiator a hole in one of your cooling hoses or a hole in the block which is unlikely. Try that and see if you can pinpoint it. P.S. if the water pump is bad it sometimes makes a squealing noise dead give a way. Good luck!

Q:Our house is situated on very sandy soil. I suspect that my water pump may be getting clogged with sand and silt and other debris. The water flow from the sinks and showers often stops randomly in the middle of the water running only to turn on maybe 30 seconds later. This seems to happen more and more frequently now where as a year ago and beyond it never occurred. Any suggestions?: I guess you are on a well system. If that is the case then you for sure have a problem with your pump. Good luck.
